Spiniferites bentorii var. bentorii
Spiniferites bentorii var. bentorii
Autonym.
Holotype: Rossignol, 1964, pl.1, figs.3,7–8.
Age: Pleistocene–Holocene.
Holotype: Ashdod 15/0 - 172/172.5 m
Locus typicus: Ashdod 15/0 borehole
Stratum typicum: Pleistocene-Recent
Diagnosis: Large Hystrichospere with ovoidal test and apical protruberance. Tabulation typical of the genus, very clear: 3 pentagonal apical plates 3", 6 alternately hexa- and pentagonal precingulars 6"", the sixth being triangular; archaeopyle in the third one, hexagonal and mid-dorsal; 6 hexagonal cingulars 6c, forming a laevorotatory helicoidal band; one longitudinally elongate ventral plate; 6 pentagonal postcingulars 6""", the sixth rectangular and situated at the antapex of the ventral plate; finally, one posterior intercalary 1P between the first postcingular and the last plate, viz. the unique hexagonal antapical 1"""".
Processes at the plate corners, trifurcate, each branch finely bifurcate; the two antapical dorsals are very well developed.
